Abstract
An intelligent electronic device (IED) is provided. The IED includes a metering sub-assembly and an input base module sub-assembly. The metering sub-assembly is hinged to the input base module sub-assembly, where when in an open position, various cables, connectors, and input/output cards/modules are accessible. Various input/output cards/modules are interchangeable to add/change functionality and/or communication capabilities to the IED. In one embodiment, a communication card is provided with at least one antenna disposed internal or external to a housing of the IED.
Claims25
An intelligent electronic device for monitoring power usage of an electrical circuit comprising:
- a housing including an interior;
- at least one sensor coupled to the electric circuit, the at least one sensor measures at least one parameter of the electrical circuit and generates at least one analog signal indicative of the at least one parameter;
- at least one analog to digital converter coupled to the at least one sensor, the at least one analog to digital converter receives the at least one analog signal and converts the at least one analog signal to at least one digital signal;
- at least one first processor that receives the at least one digital signal and calculates at least one power parameter of the electrical circuit;
- and
- a removable communication card disposed in the interior of the housing that receives the calculated at least one power parameter from the at least one processor and wirelessly transmits the calculated at least one power parameter to at least one other device, the communication card including at least one first antenna and at least one second antenna, wherein the at least one first antenna is configured as a main antenna and the at least one second antenna is configured as a diversity antenna;
- wherein the communication card receives the at least one analog signal via the at least one first antenna and/or the at least one second antenna and the communication card further comprises at least one second processor that determines which of the at least one first and the at least one second antenna is receiving a strongest signal and selects the determined antenna for communications to the at least one other device.
